This document proposes generating electricity from wind turbines mounted on fast moving vehicles like trains. It describes different turbine designs that could be fitted to trains, including J-shaped turbines, and how they would capture and compress wind to drive generators. The turbines could power train compartments or batteries and excess power could be fed back into the electric grid. Mounting turbines on India's large fleet of trains could generate a substantial amount of renewable energy each year.

2. DIFFERENT ALTERNATIVE OPTION FOR GENERATING
ELECTRICITY FROM FAST MOVING VEHICLE :-
Now a days power from fast moving vehicle can be produced this
ways:-
 Frictional energy generated by applying brake .
 By piezoelectric material from the movement in vehicle or
pressure from vehicle.
 A fast moving vehicle compresses the air in the front of it and
pushes the air from its sides thereby creating a vacuum at its rear and
its sides as it moves forward.
 Induced rotational energy when a vehicle i.e train ,aero plane
passes by the turbine.
 But here we will discuss about a method in which wind strike
the turbine directly mounted on train.

3. WHY THIS?
 The fixed wind powered electricity generation systems in use, till
now are dependent on wind direction and the force of the wind.
 But the wind is not available at all place and all time through out the
year.
 Therefore, there exists an immense need of a system for generating
electricity from wind induced by moving vehicles, trains or
airplanes, which is available through out the year at various places
and with sufficient force of wind.

4. Rotor and its alternatives
 As traditional wind turbine are difficult to fit in the
top of the train , another kind of turbine called j-
shaped wind turbine can be fit on train as shown in
fig .
 These are strong and are designed to operate at high
wind velocity of appox. 120 km/hr.
 It’s Start-up Wind Speed is 2.9mph (1.3m/sec) ,Cut-
in Wind Speed is 5.6mph (2.5m/sec), Survival Wind
Speed is 134.3mph (60m/sec).
 It also can be modified to increase rated speed.

5. Features and effect of this turbine:-
 Rotates regardless of the wind direction, and begins operation in
a gentle breeze.
 Highly resistant to strong winds, and also robust enough to
survive typhoons or hurricanes.
 Lightweight and simple structure designed for ease of
transportation, construction and maintenance.
 Low-noise, low-vibration operation.
 Requires only a limited space to install.
 Resistant to lightning-induced damage thanks to the
employment of aluminum blades.
 Mass production is possible.
 Highly customizable.
 Design helps to avoid bird strikes.
 All materials recyclable.
 Installation can be designed not to damage scenery.

6. INSTALLATION OF TURBINE ON TRAIN:-

7. METHOD:-
 The front tube is large and rear tube is of small
diameter.
 So when train moves the wind flows in opposite
direction of motion of train.
 The wind is collected in large tube and compressed in
the rear tube to produce required density of wind for
electricity production .
 The density of air can be adjusted by fitting a valve in
the tube.

8. Conversion of energy
 The generator is the unit of the wind turbine that transforms
mechanical energy into electrical energy.
 The blades transfer the kinetic energy from the wind into rotational
energy in the transmission system, and the generator is the next step
in the supply of energy from the wind turbine to the electrical grid.
 The wind turbine may be connected to an electricity generator. The
generated electricity may to be stored in batteries from which energy
may be used as per the need.

9. Where it can be used?
 These can be designed to power small units like compartments of
train, recharging batteries etc.
 It is also quite easy to imagine how a specially designed wind turbine
like this could sit on top of the train or at front and power its engine
as you cruise along on the rail/road.
 This wind turbine can be developed to be used as an alternative
means to recharge communications equipment too.
 It can be connected to our national grid in every railway track.

10. conclusion
 There are 14,300 trains operating daily on 63,000 route kilometers of
railway in India. This technique would be capable of producing
1,481,000 megawatt of power in India .
 As wind is clean source of energy it will contribute to enviromental
protection.
 Cost of production will be low.
 So we can still hope for a better future.
